Description

Technical Field

[0001] The utility model relates to the technical field of wound dressings, in particular to a hydrogel wound dressing. Background Art

[0002] Band-aids are the most commonly used surgical drugs in our lives. They are composed of absorbent pads, tapes, and anti-adhesive paper. The current absorbent pads are generally non-woven fabrics, and when used, the absorbent pads will be in close contact with the wound. In order to prevent the absorbent pads from adhering to the wound, a thin film such as polyethylene is applied to the outermost of the absorbent pads. However, this greatly reduces the water absorption effect of the absorbent pads, resulting in the inability to absorb the wound exudate in time, causing secondary contamination of the wound and delaying the recovery time.

[0003] Secondly, the absorbent pad cannot be seen on the top of the band-aid, and the left and right anti-adhesive papers need to be torn open a little and flipped over to see the position of the absorbent pad. The absorbent pad needs to be placed on the wound when applying it, so it needs to be flipped over several times to ensure that the absorbent pad can be placed on the wound. Moreover, when adjusting the position, the anti-adhesive paper may be stuck back, or all the anti-adhesive papers need to be torn off before adjustment. However, when adjusting the position, the tape may stick to the skin from time to time, making it inconvenient to adjust. Summary of the invention

[0004] The utility model aims to provide a hydrogel wound patch. Compared with non-woven fabrics, the hydrogel layer will not adhere to the wound and has a good water absorption effect, and can moisturize and promote wound healing. At the same time, the marking line is set so that the approximate position of the hydrogel layer can be known on the top of the main body, so that the first release paper can be torn off and the marking line can be used for preliminary positioning and pasting, and then the second release paper can be torn off to paste the main body on the human body, so that it is more convenient to paste, thereby solving the problem of poor water absorption effect of the existing wound patch and the position of the non-absorbent pad can be seen on the top of the wound patch.

[0005] The purpose of the utility model is achieved in this way:

[0006] A hydrogel wound dressing comprises an adhesive tape, wherein a hydrogel layer is arranged in the middle of the bottom of the adhesive tape;

[0026] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-Figure 6 As shown, a hydrogel wound dressing comprises an adhesive tape 1, and a hydrogel layer 2 is arranged in the middle of the bottom of the adhesive tape 1. The hydrogel layer 2 is made of hydrogel, and the hydrogel is a gel with high water absorption and high water retention. Therefore, compared with non-woven fabrics, the hydrogel layer 2 will not adhere to the wound and has a good water absorption effect, and can retain moisture and promote wound healing.

[0028] At the same time, a marking line 11 is provided at the top of the tape 1 corresponding to the hydrogel layer 2 , and a release paper 1 3 and a release paper 2 4 are provided at the bottom of the tape 1 along the length direction, and the width of the release paper 1 3 is smaller than the width of the release paper 2 4 .

[0029] Therefore, in actual use, the adhesive tape 1 is pasted on the human body by tearing off the anti-adhesive paper 1 3 and matching the marking line 11 for preliminary positioning, and then pasting the adhesive tape 1 on the human body by tearing off the anti-adhesive paper 2 4. Compared with the existing ones, the present invention is more convenient for pasting. That is, it does not need to be turned over for adjustment many times, but the preliminary positioning can be done by comparing the marking line 11 and the position of the wound.

[0030] Moreover, the existing setting of two left and right tapes is not very convenient for one person to tear off two tapes at the same time when the wound on the hand needs to be pasted. If one tape is torn off in advance, the tape may stick to the skin from time to time when the position is adjusted. The utility model adopts the setting along the length direction and the marking line setting. When initially positioning, a small tape is torn off first and cooperates with the marking line 11 to achieve initial positioning. Finally, the large tape is torn off when pasting, which is more convenient.

[0031] Furthermore, there are two marking lines 11 , and the distance between the two marking lines 11 is equal to the length of the hydrogel layer 2 .

[0032] At the same time, a waterproof layer is arranged on the top of the tape 1, so it is waterproof, and the tape 1 is a breathable tape, so it is breathable, thereby bringing comfort to the user and avoiding problems such as skin whitening and bacterial infection caused by airtightness.

[0033] The waterproof layer can be a waterproof film or a waterproof coating, and the breathable tape can be a PE microporous breathable tape or a zinc oxide (adhesive plaster) breathable tape.

[0034] like Figure 3 and Figure 4 As shown, the hydrogel layer 2 is transparent, a reversible shielding portion 5 is provided on the top of the adhesive tape 1 , and a through hole 12 is opened in the adhesive tape 1 .

[0035] Therefore, in actual use, the wound can be observed by turning the shielding portion 5 outward and looking through the through hole 12 and the hydrogel layer 2, and can be replaced in time when needed.

[0036] At the same time, the related structures of the shielding part 5 are diverse, which can be: first, a groove 13 is opened on the top of the tape 1 for the shielding part 5 to be placed, and there are two marking lines 11 located on both sides of the shielding part 5, and the distance between the two marking lines 11 is equal to the length of the hydrogel layer 2.

[0037] Moreover, a U-shaped traceless glue is arranged at the bottom of the shielding portion 5, and the through hole 12 is located in the traceless glue. Through such a layout, the through hole 12 is not affected while being connected, and a waterproof part such as a layer of absorbent cotton is arranged between the inner wall of the groove 13 and the side wall of the shielding portion 5, thereby preventing water from entering from the through hole 12, thereby affecting the water absorption effect of the hydrogel layer 2.

[0038] like Figure 6 As shown, a groove 13 is provided at the top of the tape 1 for placing the shielding part 5, and convex edges 51 are provided on both sides of the shielding part 5, and a marking line 11 is provided at the top of the shielding part 5, and the bottom of the convex edge 51 and the top of the tape 1 are connected and separated by traceless glue.

[0039] Therefore, in actual use, the convex edge 51 can cover the connection gap between the shielding portion 5 and the groove 13, thereby preventing water and other objects from entering through the connection gap between the shielding portion 5 and the groove 13.

[0040] like Figure 4 As shown, at least one of the two ends of the top of the adhesive tape 1 is provided with a flippable hand-held portion 6, and the hand-held portion 6 and the adhesive tape 1 are connected and separated by traceless glue.

[0041] Therefore, in actual use, when the hand-held portion 6 is turned outward, the tape 1 can be separated from the human body by pulling the hand-held portion 6 outward, so that there is no need to hold the separation tape 1, which is more convenient. Secondly, the traceless adhesive of the utility model is an existing double-sided adhesive tape made of special materials that can be repeatedly pasted and will not leave any residue on the product when peeled off.

[0042] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. At the same time, the utility model is not limited by the above embodiments, so without departing from the principle and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model claimed for protection.
